Serum CatD activity as a marker of healthy endogenous phagocytosis and remodeling was impaired in patients with new-onset cardiac dysfunction, and lower levels of serum CatD were associated with MACE at the 6-month post-MI follow-up.

Coronary artery anomalies are rarely encountered in general population. Gender may play a role in the types and incidence of coronary artery anomalies, although the effect of gender is not well established. In the present study, we therefore aimed to investigate the frequency and location of various types of coronary artery anomalies and their correlation with gender. We assessed retrospectively the coronary angiography movies of 7,810 patients (2,214 females and 5,596 males), the method of which is distinct from the earlier studies with angiographic archive records. We defined and classified the coronary artery anomalies according to their origin, course (myocardial bridge), and termination (fistula). The incidence of coronary artery anomalies was 3.35% (262 of 7,810): 130 individuals with anomalous origin (1.66%), 105 individuals with myocardial bridges (1.34%), and 27 with fistulas (0.35%). The frequency of the coronary artery anomalies was significantly higher in the females than the males ( p = 0.001). Of the coronary artery origin anomalies, the circumflex and the left anterior descending artery originating from separate ostia in the left aortic sinus were higher in the females compared to the males (P < 0.001). In contrast, the frequency of myocardial bridges was higher in the males (P = 0.01). No gender difference was detected in fistulas. Thus, gender affects the types of coronary artery anomalies, except for fistulas. The determination of the presence of the coronary artery anomalies during the coronary angiography is critical for the planning of the treatment and for the proper clinical follow-up of patients.

Background/Aim: It is not known why cerebrovascular and cardiovascular ischaemic events are less frequently observed in heterozygous beta thalassaemia (HBT) patients than in the general population. However, we previously reported that serum levels of some platelet function markers, i.e. soluble CD40 ligand and soluble P-selectin, are lower in patients with HBT than in controls. A high mean platelet volume (MPV) is an indicator of in vivo platelet activation and may indicate a tendency to thrombosis. We investigated whether MPV is lower in HBT patients than in controls. Methods: Forty-eight patients with HBT were compared with 51 controls matched for gender, age, and BMI for MPV in a cross-sectional study. Results: The MPV was within the normal range and higher in the HBT group (9.64 ± 1.20 vs. 9.07 ± 082 fL, p = 0.006). The 2 groups were similar in terms of atherosclerosis risk factors and medications. After linear regression analysis, the MPV was correlated with HBT, sensitive CRP, and BMI. Conclusion: The higher MPV in patients with HBT could indicate platelet activation, and this may represent a dilemma. Higher MPV in the HBT group might have resulted from higher sympathetic nervous system activity, mild ineffective erythropoiesis, and haemolysis.
